See Figure 4-17 for the hardware sequence when installing the lugs to the bus bars.Tighten the bolt to the torque value listed in Table 3-10.Proceed to paragraph 4.3.5.Figure 4-17. Typical Bus Bar Barrel Lug Mounting – Hardware Assembly Sequence4.3.5 150 kW and 200 kW Output WiringTo install wiring to connections:1. If not already open, open the front door (see Figure 4-1) by lifting the latch from the bottom and turning tothe right (counterclockwise) and swing the door open.2. Loosen the screws securing the inside distribution panel door and swing the door open.3. Loosen the screws securing the inside trim plate(s) and remove the plate(s). Retain trim plate(s) andhardware for later use.4. If wiring an IAC-D with distribution panels, continue to Step 5; if wiring an IAC-D with subfeed breakers oran output breaker, skip to Step 7.5. Install customer-supplied branch circuit breakers into the distribution panel (see Figure 4-11 orFigure 4-18). Use Cutler-Hammer bolt-on type BAB or QBHW breakers.6. Route output cables to the branch circuit breakers and wire the branch circuits according to the branchcircuit breaker manufacturer's ratings and instructions, and national and local electrical codes (input isprewired to the panelboard). See Figure 4-11 or Figure 4-18, for neutral and ground terminal locations. Seeparagraph 3.2.2, Table 3-6 and Table 3-10 for IAC-D wiring and termination requirements.NOTE Conical washers are special purpose washers that look similar to flat washers,except for a slight conical shape. When installing conical washers, the top of thedome should be next to the bolt head and the base of the washer should be againsta flat surface such as a bus bar, flat washer, or large terminal.NOTE When wiring branch circuits, begin adding conduits at the back of the bottom or topconduit landing plates to simplify future circuit additions.Hex NutConical WasherLugBus BarFlat WasherBolt HeadLugFlat WasherDouble Lug Installation
